The government is considering increasing electricity charges to help cover damages payments to people who have suffered losses on the ongoing crisis at the Fukushima Daiichi nuclear plant of Tokyo Electric Power Co., government sources said Tuesday.

It is planning to increase the tax on electricity source development, which is collected from consumers as part of electricity charges, and use the hike for providing a portion of the damages payments that TEPCO may not be able to shoulder, they said.

When was the last time a utility had to raise rates because of an accident at a natural gas or coal fired plant?

One of the more surprising victims of this weekend's dramatic tornado flurry that ravaged numerous states causing the deaths of 45 people, were two nuclear reactors operated by Dominion Resources in Surry County, Virginia on April 16. Luckily, it appears that the shutdowns have been contained. From Reuters: "Dominion Virginia Power said the two nuclear reactors at its Surry Power Station shut down automatically when a tornado touched down and cut off an electrical feed to the station.

I keep telling these guys that reactors designed without intrinsic safety are accidents waiting to happen. What do I mean by intrinsic safety? The reactor can cool down on its own without any electrical power. Only designs that meet that criteria should be approved for future construction.

The radiation levels inside the Nos. 1 and 3 reactor buildings at the crippled Fukushima Daiichi nuclear power plant were up to about 57 millisieverts per hour as of Sunday, the government's nuclear safety agency said Monday, acknowledging that such a level imposes time constraints on restoration work that must be conducted there.

And of course that is just one measurement inside the buildings. There are no doubt hot spots where a worker has even less time to get something done. It appears that the Japanese only surveyed low radiation areas.

According to TEPCO, there were a lot of debris inside the Reactor 3 building, and the robots had a hard time moving forward and didn't go much beyond the door.

TEPCO also did the dust sampling.

Part of the reason why they had the robots enter through the north door was because of the high radiation level at the south door.

On April 16, the radiation level at the south door to the Reactor 1 building was measured at 270 milli-sievert/hr. The distance between the north door and the south door is about 30 meters, according to TEPCO. The radiation right outside the north door was also measured on April 16, and it was 20 milli-sievert/hr.

This was the first time the radiation level was measured inside the Reactor buildings (other than Reactor 4 building) since the March 11 earthquake.

The annual limit for radiation exposure for nuclear plant workers has been raised to 250 milli-sievert/year after the Fukushima I Nuke Plant accident. Working in the Reactor 3 building for 5 hours would exceed that number.

At the Fukushima Daiichi nuclear plant, high levels of radiation have kept workers from approaching the buildings housing the first 3 reactors, which lost their cooling functions in the March 11th earthquake and tsunami.

On Friday, the highest radiation level measured outside the double-entry doors of the Number 1 to 3 reactor buildings was 2 to 4 millisieverts per hour.

Radiation levels measured between the double doors of those reactor buildings was 270 millisieverts in the Number One reactor, 12 in Number 2, and 10 in Number 3.

The radiation level detected at the Number One reactor exceeds the national exposure limit of 250 millisieverts for nuclear contract workers.

Just another minor obstacle for the Japanese plan to have this disaster wrapped up in 6 to 9 months.

And speaking of obstacles for the workers. Even robots can't stand the working conditions.

TEPCO couldn't get enough data on the radiation level in the Reactor 2 building. Two remote-controlled robots went through the door to the Reactor 2 building on April 2. But after measuring 4.1 milli-sievert/hr near the door, the camera lens quickly became foggy due to high humidity (94 to 99%) and couldn't record the radiation level.

Too steamy? I wonder what constitutes a steamy novel for a robot? And did you know that robot is synonymous with serf? They are too dumb to know they are being exploited. Probably a good thing.

In Japan the vegetables don't just get showers before they are measured for radiation. The must also get timely showers.

Professor Kunihiko Takeda of Chubu University says in his April 19 blog post that:

after the Fukushima I Nuke Plant accident the government suddenly changed the procedure to measure the radiation level in vegetables, and issued a notice that "the vegetables to be analyzed for radioactive materials should be taken out of the boxes, washed carefully under running water, and then analyzed."

That caused the total loss of confidence in the safety of the vegetables.

The reason? It is easy to remove the radioactive materials on the vegetables when they are about to be shipped, soon after having been harvested. By the time they reach the consumers, it would be difficult to remove the radioactive materials as they stick fast on the surface or have penetrated inside the vegetables.

You can't trust the radiation level numbers on vegetables and other farm produce announced by the government.

There are all kinds of ways to fake the numbers. You just learned another one.

The operator of the Fukushima Daiichi nuclear power plant says it will examine the seabed off the facility to ensure that no plutonium has leaked into the ocean.

Tokyo Electric Power Company said on Monday it will conduct the inspection as plutonium is heavier than other radioactive materials and could have accumulated on the floor.

Plutonium is a radioactive substance that could cause lung cancer if inhaled.

TEPCO detected earlier small quantities of plutonium in the soil around the plant. But it said the amount is too small to harm human health.

Unless it gets in the lungs.

The Japanese are concerned about the safety of their drinking water. A commission has been appointed to whitewash the issue.

Japan's health ministry is to set up a panel of experts to discuss ways to safeguard tap water from radioactive contamination.

The move comes after radioactive iodine at levels higher than national limits was detected temporarily in tap water in parts of Fukushima and Ibaraki prefectures amid the disaster at the Fukushima Daiichi power plant.

The ministry on Tuesday held a meeting of advisors including environment experts and water utility industry representatives to discuss countermeasures.

Some participants asked that tap water safety be promoted publicly whenever radiation levels are low. Others said water in rivers and reservoirs should also be tested for radiation.

Ah. Yes. Promote safety when radiation levels are low. When they are high? Don't mention it.

I have a policy these days of writing something happy after I do one of these updates. Otherwise the news is just too depressing.

OK.
I get paid from Amazon if you order from any of the links provided. I will give you an honest opinion of any products I have ordered if I blog about them.
If you don't trust me read the Amazon reviews. If there is no review you are on your own.
If you pay me enough and promise to cover my lawyers fees I may say something nice about you. Or I may not. Enough is generally more than you can afford. Unless you have a a really really big bank account or more that a few large gold bars under the mattress.
If you do pay I expect to be transported to a country with no extradition treaty with the US.
If I review a book it may be because the author or publisher sent me a review copy. Other wise I will quote a review of some one else. If I say a product looks interesting it is because it interests me. Sometimes I will link to books so you can educate yourself on a subject and so I can make some off the sale.
If some one employs me I will probably say good things about them as long as the money keeps coming. Or I may say nothing. To keep out of trouble with their lawyers.
That covers most of what I can think of. I'm getting old and sometimes I don't think of everything.
And if you have read this far please Buy Something From Amazon. I can use the money - well actually I will use the proceeds to buy something from Amazon. I get a better deal that way.
